Abstract: An absorbent article having a void space for receiving bodily exudates comprises an elongate slit opening in communication with the void space. The elongate slit opening includes elasticated region disposed along longitudinal side edges of the slit opening which maintain longitudinal and lateral alignment and Z-direction proximity with a point of discharge on a wearer during use. The elasticated regions contain stored elastic energy producing tensile forces which are distributed laterally away from the slit opening enabling the edges to deflect and allow bodily exudates to pass through the slit opening to the void space.

Title: Combination of amines and vanadium (iv)/(v) compounds for the treatment and/or prevention of diabetes mellitus
Inventor: ZORZANO OLARTE ANTONIO
IPC: A61K33/24
Filed: 2001-11-06
Abstract: Combinations including vanadium (IV)/(V) compounds and pharmaceutically acceptable amines selected from amongst the group of semicarbazide-sensitive  amine oxidase substrates (SSAO) are imitators of insulin. The preferred vanadium (IV)/(V) compounds are vanadyl salts, vanadyl complexes and vanadat es (for example, sodium orthovanadate ). The preferred amines are tyramine and benzylamine. As a result of a synergy between the vanadium compound and the amine disclosed herein, an effective concentration of vanadate in said combination is lower than the one corresponding to vanadate alone. Consequently, the combination has a much lower toxicity than the vanadium compound alone, as is already known, which provides a crucial advantage of t he combination for its use in the treatment and/or prevention of Diabetes mellitus.

Title: Photopatternable sorbent and functionalized films
Inventor: GRATE JAY W
IPC: C09D183/04
Filed: 2001-10-31
Abstract: A composition containing a polymer, a crosslinker and a photo-activatable catalyst is placed on a substrate. The composition is exposed to a predetermined pattern of light, leaving an unexposed region. The light causes the polymer to become crosslinked by hydrosilylation. A solvent is used to remove the unexposed composition from the substrate, leaving the exposed pattern to become a sorbent polymer film that will absorb a predetermined chemical species when exposed to such chemical species.

Abstract: A phase mask, for writing fiber Bragg gratings (FBG) in an optical fiber, adjusts the amplitude and the phase of the FBG, while maintaining a constant mean index of refraction of the fiber in a single pass. Specifically, the phase mask embodies the amplitude information so that the amplitude information is an integral part of the phase mask and preferably cannot be separated from the phase information. A first embodiment employs a reflective or opaque surface, defining a window, on the substrate of a phase mask controlling the amplitude of light passing through the phase mask. Another embodiment employs a polygonal shaped grating region an a clear substrate. A third embodiment interleaves regions of grating and smooth substrate surface. Preferred embodiments employ two areas of gratings with the areas disposed: perpendicularly, out of bandwidth or out of phase, relative to each other or additive.

Abstract: The present invention is directed to a respiratory helmet. The helmet is designed to provide protection to a user's cranium area. The helmet also has a visor designed to provide protection to the user's face area, an air intake system, and a parallel elliptical rail system. The visor can be positioned on the helmet, in front of the user's face area, and any position in between. The area between the visor, when the visor is positioned in front of the user's face area and the face area is called the breathing zone. The visor has at least two wheels, a top side and a bottom side wherein the bottom side is positioned closer to the user's chin when the visor is positioned in front of the user's face. The air intake system has an intake unit that receives a gaseous medium from a gaseous medium supply system or the ambient air into the helmet, and the intake unit directs the gaseous medium toward the breathing zone. The parallel elliptical rail system allows the visor to move in an elliptical motion. Each rail receives at least one wheel of the visor, and is designed to decrease the accumulation of particulates on the rail.

Title: Anti-slip glass fibre-reinforced plastic-plate
Inventor: WORM JOACHIM
IPC: B32B17/04
Filed: 2003-10-28
Abstract: The invention relates to a glass fibre-reinforced plastic-plate which is provided with an anti-slip coating, consisting of resin and sand, as well as a production process of such a plate. The process according to the invention is a continuous one and does not require manual production steps. Initially, for the production a resin is bonded (10) with glass-fibre mats to a glass fibre-reinforced laminate as base material (20) and heated. As is conventional, the plate (20) is covered on both sides with carrier films (11, 12). In the subsequent phase of cooling-down (13) the point in time is waited for in which the plate (20) is in actual fact partly gelatinized, but the surface which is supposed to be coated is not yet completely cured. In this stage the upper carrier film (11) is pulled-off and a premixed coating compound consisting of resin and sand is applied (18) from above onto the base material (20). Alternative to the application of a premixed coating material, the resin and sand can be applied separately. Dissolver-vapours emerging at this stage can be drawn-off mechanically. In a circulating air drying oven (14) the heating-up to the final curing occurs.
